I have no idea what this says as I don't read Japanese, but I think this is one of the tastiest things I've found in ages. See, there's a tradition we have-- whenever we go to an Asian Market of any sort, we chose one thing that has no English on it at all, and we try it. For one, it expands our horizons and makes up bolder, and for two, it lets us sample things we never would have tried before. This is one of the good things to come out of that little experiment.
It tastes very Japanese; I'm chalking it up to the seaweed and sesame seeds in the broth it forms when you add the hot water. It's savory without being too salty, mild without being bland. Reminds me more of miso than of tea, but has a lovely greenish color like a really perfect cup of green tea. It's easy to make, and it's tasty, and served over a pile of rice like the picture on the back shows, it's remarkably filling.
I had these little packets for a long time before I got up the nerve to try one, and now I'm sad I waited so long, because it really is delicious. My only regret is that I have no idea what it's called in Japanese, so I can't search for it online when I have no access to the Market.
You've found me! Assuming, of course, that you're looking for the short, usually-redheaded, tea-drinking, cat-loving, alternatively-spiritual, attempted-optimist who writes fantasy, science fiction and various acts of academia.
